NIH's On-Campus Beagle Lab
For nearly four decades, the National Institutes of Health operated an in-house beagle laboratory at its Bethesda, Maryland campus — running septic shock experiments that advocacy groups allege killed more than 2,133 dogs. In May 2025, NIH Director Jay Bhattacharya announced the closure of the last beagle lab on NIH grounds. The closure was real. What it didn't end: NIH still funds beagle experiments at external institutions across the country.
NIH's Role in Animal Research
The National Institutes of Health is the largest public funder of biomedical research in the world, with a budget exceeding $47 billion. NIH operates two tracks of research: extramural (grants to universities, hospitals, and private labs) and intramural (research conducted on NIH's own campus in Bethesda, Maryland). The beagle lab that closed in May 2025 was intramural — experiments run by NIH staff, on NIH grounds, using NIH-purchased dogs.
NIH animal research is governed by Institutional Animal Care and Use Committees (IACUCs), the Office of Laboratory Animal Welfare (OLAW), and the USDA Animal and Plant Health Inspection Service under the Animal Welfare Act. NIH's Bethesda campus is registered with USDA under certificate number 51-F-0016.
The On-Campus Beagle Lab: What It Did
The documented beagle work at NIH was conducted by the Critical Care Medicine Department at the NIH Clinical Center (Building 10 on the Bethesda campus). Multiple peer-reviewed papers list Building 10 room numbers (e.g., Room 2C145, 2C136) as the physical location of the canine sepsis research infrastructure.
The Canine Septic Shock Model
Across multiple publications spanning decades, NIH researchers describe a controlled large-animal model intended to mimic aspects of human septic shock. The recurring elements of the model include:
- Induction of pneumonia/sepsis: Purpose-bred beagles were challenged with bacteria (commonly Staphylococcus aureus) to induce septic shock via pneumonia.
- Invasive instrumentation: Multiple venous catheters and tracheal tubes were inserted for monitoring and intervention.
- Prolonged critical-care monitoring: Dogs underwent intensive supportive care and repeated physiologic measurements over extended periods, described as ICU-like conditions.
- Vasoactive drug testing: Dogs were randomized to receive different vasoactive infusions to study cardiovascular responses during sepsis.
Study Sizes and Scale
Individual published experiments used dozens of animals at a time. A widely cited physiology paper describes 38 purpose-bred beagles in a single study. A 2024 article from the same NIH research line describes beagles receiving bacterial challenge and randomized vasoactive infusions with sample sizes in the tens. The intramural funding mechanisms tied to this work include project numbers Z01 CL008072, Z01 CL008074, and ZIA CL008074.
The “2,133+ Beagles” Claim
What White Coat Waste Alleges
White Coat Waste Project (WCW) alleges that at least 2,133 beagles died in NIH septic shock experiments — described as a floor based on their analysis of published literature and FOIA-obtained records. WCW states the work was conducted in-house at the NIH Clinical Center and was continuously funded since at least 1986. WCW-aligned media accounts describe FOIA materials including necropsy reports from 41 beagles, asserted to document infection-induced sepsis and sometimes hemorrhage-related procedures.
What Can Be Independently Verified
The existence and nature of NIH's canine sepsis research is strongly supported by the peer-reviewed literature. The specific cumulative count of “2,133” is harder to verify independently for three reasons: (1) the figure is WCW's derived result from publication-based counting, not a number stated in an NIH annual summary; (2) the most straightforward verification pathway — USDA annual reports by facility across decades — has not been publicly compiled end-to-end; (3) published studies show individual experiments using dozens of animals, making a multi-decade total in the low thousands plausible in magnitude, but plausibility is not the same as a verified total.
The May 2025 Closure
NIH Director Jay Bhattacharya publicly announced that NIH had ended on-campus beagle experiments and closed the “last beagle laboratory on its campus.” A WJLA investigative report described the shutdown as occurring just days before their June 2025 publication, with the final experiment killing five dogs.
What Drove the Closure
The closure reflects both an internal decision by NIH leadership and sustained external pressure spanning years:
- Congressional scrutiny: In January 2024, a bipartisan group of 23 lawmakers sought detailed information from NIH about dog and cat experiments at NIH-funded labs.
- White Coat Waste Project campaigns: Years of FOIA requests, publication analysis, and media pressure targeting NIH's in-house beagle experiments.
- PETA legal action: PETA described a multi-year campaign including a “landmark lawsuit” in 2021 targeting NIH sepsis experiments.
- Public opinion shift: Gallup polling shows Americans are now roughly split on whether medical testing on animals is morally acceptable, with acceptance declining substantially since 2001.
What the Closure Means — and Doesn't Mean
- In-house beagle experiments on the NIH Bethesda campus
- The ~40-year canine septic shock research program
- Direct NIH procurement of purpose-bred beagles for on-site use
- Building 10 canine research infrastructure
- NIH extramural funding of beagle experiments at universities and private labs
- NIH-funded grants that may involve beagle testing at CROs
- Other federal agencies' beagle research (VA, DOD, EPA, FDA)
- The broader commercial pipeline of purpose-bred beagles for research
The Broader Pattern: Federal Agencies and Beagles
NIH was not the only federal entity using beagles. The pattern of government-funded beagle experimentation extends across multiple agencies, each with its own timeline of scrutiny and reform:
Congress directed the VA to end experiments on dogs, cats, and primates by 2026. VA dog usage had already declined from approximately 700 to just 9 dogs over a 19-year period before the legislative mandate.
EPA committed to eliminating mammalian testing for pesticides by 2035. The target was reinstated in January 2026 after an earlier pause.
In April 2025, FDA announced a plan for animal studies to become “the exception rather than the norm” within 3–5 years, starting with monoclonal antibodies. The FDA Modernization Act 2.0 (2022) removed the 1938 mandate that required animal testing, allowing sponsors to submit non-animal data.
The Fauci / NIH Beagle Controversy
In 2021, the NIH beagle issue became a national flashpoint when White Coat Waste Project published allegations about NIH-funded experiments involving beagles — including claims about sandfly experiments in Tunisia and the in-house septic shock program. The controversy was amplified by bipartisan congressional letters and became entangled with broader political battles over Anthony Fauci's leadership of NIAID.
The political dimension created a complicated dynamic: it drew unprecedented public attention to beagle testing, but also made the issue polarizing in ways that sometimes obscured the underlying science and animal welfare questions. Advocacy groups including WCW, PETA, and the Physicians Committee for Responsible Medicine each framed the issue differently — WCW emphasizing taxpayer waste, PETA emphasizing animal cruelty, PCRM emphasizing scientific alternatives. The convergence of these campaigns, combined with congressional pressure, ultimately contributed to the May 2025 closure.
Who Supplied the Beagles
Determining exactly which breeders supplied NIH's on-campus lab requires procurement documentation or FOIA releases naming vendors. The accessible public record primarily supports supplier linkages through investigative and advocacy accounts rather than direct NIH purchase orders.
Envigo RMS, LLC pleaded guilty to conspiring to knowingly violate the Animal Welfare Act at its Virginia beagle breeding facility. DOJ secured the surrender of over 4,000 beagles in 2022. Some reporting asserts NIH sourced beagles from Envigo, but this is stated in advocacy accounts rather than confirmed through NIH procurement records.
References in advocacy reporting indicate concern about beagle sourcing from Marshall, but accessible sources do not include a primary NIH procurement document naming Marshall as the vendor for the Clinical Center dog lab.
Late 2025 advocacy materials call on NIH and FDA to avoid funding beagle procurement from Ridglan. These sources do not prove Ridglan supplied NIH's on-campus lab, but reflect ongoing concern about the broader NIH-funded research pipeline.
